Re: no sound in non-root user

Have you added yourself to the audio group?

Re: no sound in non-root user

I add my account to the audio group now, but I still can hear the sound.
I restart the computer to see if I have sound now.

I want to know what command can I use to display all the info of a user. And where can I get the manual about user management.

Re: no sound in non-root user

No problem, fluke.

The command

groups

will show the groups to which the logged-in user belongs, and

gpasswd

adds/deletes users to/from groups.

useradd
usermod
userdel

add/modify/delete users on your system, although

adduser

is usually used instead of useradd - it's just a more user-friendly version.

All the above except adduser have man pages.

Re: no sound in non-root user

used usermod to modify the password of a user, but I find that the password was wrong.
I now know the -p option must followed by a crypted password.
But how can I get crypted password quickly?
I don't know, so I gonna write a c program to generate the crypted password.
Any good ideas?
